6840# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
6841# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
6842# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
6843#
6844# Of course, Automake must honor this variable whenever it calls a
6845# tool from the auxiliary directory.  The problem is that $srcdir (and
6846# therefore $ac_aux_dir as well) can be either absolute or relative,
6847# depending on how configure is run.  This is pretty annoying, since
6848# it makes $ac_aux_dir quite unusable in subdirectories: in the top
6849# source directory, any form will work fine, but in subdirectories a
6850# relative path needs to be adjusted first.
6851#
6852# $ac_aux_dir/missing
6853#    fails when called from a subdirectory if $ac_aux_dir is relative
6854# $top_srcdir/$ac_aux_dir/missing
6855#    fails if $ac_aux_dir is absolute,
6856#    fails when called from a subdirectory in a VPATH build with
6857#          a relative $ac_aux_dir
6858#
6859# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
6860# are both prefixed by $srcdir.  In an in-source build this is usually
6861# harmless because $srcdir is `.', but things will broke when you
6862# start a VPATH build or use an absolute $srcdir.
6863#
6864# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
6865# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
6866#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
6867# and then we would define $MISSING as
6868#   MISSING="\${SHELL} $am_aux_dir/missing"
6869# This will work as long as MISSING is not called from configure, because
6870# unfortunately $(top_srcdir) has no meaning in configure.
6871# However there are other variables, like CC, which are often used in
6872# configure, and could therefore not use this "fixed" $ac_aux_dir.
6873#
6874# Another solution, used here, is to always expand $ac_aux_dir to an
6875# absolute PATH.  The drawback is that using absolute paths prevent a
6876# configured tree to be moved without reconfiguration.
